The most common reasons a 2000 Plymouth Neon cruise control isn't working are failed control module, sensor or switch issues, or throttle actuation problems.
  • Sensor: A faulty or malfunctioning sensor can lead to incorrect readings, causing issues with engine performance or other systems relying on accurate data.
  • Control Module: A faulty control module can lead to erratic vehicle behavior or failure of various electronic systems due to improper signal processing.
  • Throttle: A faulty throttle body or a defective accelerator pedal position sensor may be causing inconsistent throttle response.
Proper diagnosis will determine the exact cause of your symptom, saving you money on unnecessary repairs. The diagnostic experts at RepairPal Certified shops have the right tools and experience to solve any symptom.

How much does it cost to fix a 2000 Plymouth Neon cruise control isn't working?

Common Repairs

The total repair cost will vary based on the condition of your vehicle and the number of repairs needed to fix your symptom. Proper diagnosis will save you money by finding the exact repairs needed to fix your car right the first time.

When the throttle position sensor fails, the engine's computer tends to overcompensate with fuel, leading black exhaust coming from the tailpipe. There is a strong possibility of engine misfires, and the check engine light will come on.

Throttle position sensors can also develop "dead spots," or certain places along the throttle curve where it doesn't get a reading. When this happens, the above symptoms can occur but then stop when you further press or let off the gas pedal.

When the vehicle speed sensor fails or the wiring harness prevents signal transmission, the speedometer is the first thing that will stop functioning properly. This can be an intermittent issue where the speedometer only works occasionally, the speedometer may cease all function, or the speedometer may read erratically or incorrectly. Also, the traction control and anti lock brake warning lights specific to each vehicle may be illuminated, depending on the design of those systems. You may notice the vehicle hesitate to accelerate, cruise control will not function properly, and the vehicle may not shift properly through all of the gears.

In the event that a wheel speed sensor fails, the ABS, traction control system (TCS) and manufacturer specific stability control system lights will illuminate, informing the driver that the systems are disabled. The vehicle will be more prone to tire slip, and normal driving patterns may need to be adjusted to correct for the loss of computer control. On older vehicle's, the speedometer can be affected, causing illumination of the check engine light as well.

What steps should I take to diagnose the non-functioning cruise control on my 2000 Plymouth Neon?

To diagnose the non-functioning cruise control on your 2000 Plymouth Neon, start with the simplest checks before moving on to more complex diagnostics. Begin by inspecting the fuses related to the cruise control system, as a blown fuse can often be the culprit behind the malfunction. Next, examine the brake pedal and throttle body; any issues with these components can directly affect the cruise control's operation. If these initial checks do not resolve the issue, utilize a diagnostic scanner to identify any error codes that may provide further insight into the problem. Finally, consult your vehicle's manual to locate the fuse box and ensure you are checking the correct fuses. By following this structured approach, you can effectively troubleshoot and potentially resolve the cruise control issues in your Plymouth Neon.

What are the common problems that could cause the cruise control to stop working in a 2000 Plymouth Neon?

When troubleshooting the cruise control system in a 2000 Plymouth Neon, it's essential to consider several common problems that could lead to its failure. One of the first things to check is the fuse; a blown fuse in the vehicle's fuse box is often a straightforward fix that can restore functionality. Additionally, the cruise control switch located on the steering wheel may become faulty over time, preventing the system from engaging properly. Another critical aspect to inspect is the vacuum system, as any leaks can disrupt the operation of the cruise control. The speed sensor also plays a vital role; if it malfunctions, it can provide inaccurate speed readings, which may cause the cruise control to fail. Furthermore, issues with the brake light switch can interfere with the cruise control system, as it is designed to disengage when the brakes are applied. Lastly, a malfunctioning throttle cable can hinder the cruise control's ability to maintain speed. By systematically checking these components, DIY enthusiasts can effectively diagnose and potentially resolve the cruise control issues in their Plymouth Neon.

How urgent is it to repair the non-functioning cruise control in a 2000 Plymouth Neon?

When it comes to the non-functioning cruise control in a 2000 Plymouth Neon, understanding the urgency of repair is crucial for both safety and vehicle performance. While a malfunctioning cruise control system may not pose an immediate threat, it can lead to inconveniences during long drives or highway travel, where maintaining a consistent speed is beneficial. If the issue stems from minor components like a blown fuse or a faulty brake switch, it may not directly impact the vehicle's drivability. However, if the cruise control failure is indicative of underlying engine or transmission problems, it could signal a more serious mechanical issue that warrants prompt attention. Ignoring these symptoms could lead to further complications, potentially compromising safety and resulting in costly repairs down the line. Therefore, while it may not be an urgent fix, addressing the cruise control malfunction in a timely manner is advisable to ensure a comfortable and safe driving experience.
